681xzz Bearing Product Overview & Core Advantages
The 681XZZ is a miniature shielded ball bearing designed for applications demanding compact size and reliable performance. As a single row deep groove ball bearing, it excels at handling radial loads and is engineered for high-speed operation. Its key advantages include a compact design with a 1.5 mm bore, making it ideal for space-constrained assemblies, and shielded construction that offers protection against contamination. Manufactured to ABEC1 precision tolerances, this bearing provides consistent performance for a wide range of industrial and electronic applications.
681xzz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 681 | Standard designation for a miniature bearing series with a 1.5mm bore and 4mm outside diameter. |
| ZZ | Indicates the bearing is equipped with shields on both sides. This provides effective protection against solid contaminants while allowing for high-speed operation. |
681xzz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage and optimized internal geometry enables a high limiting speed of 100,000 rpm, making it a true high-speed bearing.
- Robust Construction: Components made from chrome steel (rings and balls) provide excellent wear resistance and durability under radial dynamic loads.
- Contamination Protection: The 300 series stainless steel shields on both sides help retain lubrication and exclude debris, enhancing bearing life in challenging environments.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 / 0.002mm to 0.013mm), ensuring smooth and precise rotation.
681xzz Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical Devices: Used in dental handpieces, small pumps, and diagnostic equipment.
- Office Automation: Critical components in printers, scanners, and small fans.
- Instrumentation and Gauges: Provides smooth, low-friction rotation in precision measuring devices.
- Robotics and RC Models: Suitable for joints, wheels, and small gearboxes where compact size and reliability are paramount.
